P.A.L.S Pediatric Advanced Life Support Airway management Respiratory Anatomy • Nose and mouth warms, moisten, filters air • Pharynx – Oropharynx – Nasopharynx • Epiglottis • Trachea 2 Anatomical difference between adult and pediatric • Nose – Obligatory nasal breathing – Poor tolerance to obstruction • Head – Relatively large • Tongues – Large – Loss of tone with sleep, sedation, CNS dysfunction – Frequent cause of upper airway obstruction Anatomical difference between adult and pediatric • Epiglottis – Relatively large size in children – Omega shaped – Floppy – not much cartilage • Larynx – High position – Anterior position • Cricoid cartilage – less developed and less rigid. – the narrowest part of airway • Trachea – narrower and more flexible Children are different Correct (sniffing) position for maximal airway patency Airway Positioning Opening the Mouth • Crossed-finger technique • Inspect the mouth Vomit Blood Secretions Foreign bodies 8 Crossed-finger technique for opening the airway Finger sweep maneuver Opening the Airway • Head Tilt Chin lift maneuver • Jaw thrust maneuver • Combined Remember : C-spine stabilization Head Tilt Chin lift maneuver Head-tilt/chin-lift maneuver Jaw thrust Neck trauma Combined Opening or securing the Airway • Bag-Mask Ventilation • Oropharyngeal Airway/Nasopharyngeal Airway • LMA • Combitube • ETT Oropharyngeal Airway Correct Size Insertion Oral Airway Wrong size: Too Long Oral Airway Wrong size: Too Short Oral Airway Correct size Nasopharyngeal Airway • For maintaining airway in “more awake” patients • Sits in nasopharynx and opens airway Nasopharyngeal Airway • Size: Estimate by comparing to patients little Finger • Length: Nostril to Tragus • Insertion :Lubricate Gently push posterior towards ear on same side Nasopharyngeal Airway Contraindications : Basilar skull fracture CSF leak Coagulopathy ETT as a Nasal airway Pediatric Bag-Mask Ventilation * Laryngeal Mask Airway(LMA) • • • • • • • Advanced airway Useful alternative for “difficult intubation” Easy to use Limited Paediatric use Not always successful Sits on larynx Protects lungs? When to use LMA Bag-mask ventilation is unsuccessful and endotrecheal intubation is not possible LMA Insertion LMA Insertion LMA Insertion Intubation • Larynx cephalad and anterior in children • Practitioner may need to be lower than patient and look up Intubation Age kg ETT Newborn 3 mos 1 yr 2 yrs 3.5 6.0 10 12 3.5 3.5 4.0 4.5 Length (lip) 9 10 11 12 Children > 2 years: ETT size (uncuffed): Age/4 + 4 ETT size (cuffed): Age/4 + 3.5 ETT depth (lip): Age/2 + 12 Laryngoscope Blades Macintosh Miller Airway positioning for children <2yrs Curved Blade Attaches to Laryngoscope Handle Keep in left hand Visualization of Vocal Cords Anatomy Vallecula Tongue Epiglottis Vocal cord Glottic opening Arytenoid cartilage Straight Laryngoscope Better in younger children with a floppy epiglottis Straight Laryngoscope Blade – used to pick up the epiglottis Curved Laryngoscope Better in older children who have a stiff epiglottis The tip of the laryngoscope was positioned in the vallecula.
